Quick Guide
What is CSS?
- Superior styles to HTML − CSS has a much wider array of attributes than HTML, so you can give a far better look to your HTML page in comparison to HTML attributes.
- Multiple Device Compatibility − Style sheets allow content to be optimized for more than one type of device. By using the same HTML document, different versions of a website can be presented for handheld devices such as PDAs and cell phones or for printing.
- Global web standards − Now HTML attributes are being deprecated and it is being recommended to use CSS. So its a good idea to start using CSS in all the HTML pages to make them compatible to future browsers.
Who Creates and Maintains CSS?
CSS is created and maintained through a group of people within the W3C called the CSS Working Group. The CSS Working Group creates documents called specifications. When a specification has been discussed and officially ratified by the W3C members, it becomes a recommendation.
These ratified specifications are called recommendations because the W3C has no control over the actual implementation of the language. Independent companies and organizations create that software.
NOTE − The World Wide Web Consortium, or W3C is a group that makes recommendations about how the Internet works and how it should evolve.
CSS Versions
Cascading Style Sheets level 1 (CSS1) came out of W3C as a recommendation in December 1996. This version describes the CSS language as well as a simple visual formatting model for all the HTML tags.
CSS2 became a W3C recommendation in May 1998 and builds on CSS1. This version adds support for media-specific style sheets e.g. printers and aural devices, downloadable fonts, element positioning and tables.
CSS - Syntax
selector { property: value }
Example − You can define a table border as follows −
table{ border :1px solid #C00; }
Here table is a selector and border is a property and given value 1px solid #C00 is the value of that property.
You can define selectors in various simple ways based on your comfort. Let me put these selectors one by one.
The Type Selectors
This is the same selector we have seen above. Again, one more example to give a color to all level 1 headings −
h1 { color: #36CFFF; }The Universal Selectors
Rather than selecting elements of a specific type, the universal selector quite simply matches the name of any element type −
* { color: #000000; }This rule renders the content of every element in our document in black.
The Descendant Selectors
Suppose you want to apply a style rule to a particular element only when it lies inside a particular element. As given in the following example, style rule will apply to <em> element only when it lies inside <ul> tag.
ul em { color: #000000; }The Class Selectors
You can define style rules based on the class attribute of the elements. All the elements having that class will be formatted according to the defined rule.
.black { color: #000000; }This rule renders the content in black for every element with class attribute set to black in our document. You can make it a bit more particular. For example −
h1.black { color: #000000; }This rule renders the content in black for only <h1> elements with class attribute set to black.
You can apply more than one class selectors to given element. Consider the following example −
<p class = "center bold"> This para will be styled by the classes center and bold.</p>The ID Selectors
You can define style rules based on the id attribute of the elements. All the elements having that id will be formatted according to the defined rule.
#black { color: #000000; }This rule renders the content in black for every element with id attribute set to black in our document. You can make it a bit more particular. For example −
h1#black { color: #000000; }This rule renders the content in black for only <h1> elements with id attribute set to black.
The true power of id selectors is when they are used as the foundation for descendant selectors, For example −
#black h2 { color: #000000; }In this example all level 2 headings will be displayed in black color when those headings will lie with in tags having id attribute set to black.
The Child Selectors
You have seen the descendant selectors. There is one more type of selector, which is very similar to descendants but have different functionality. Consider the following example −
body > p { color: #000000; }This rule will render all the paragraphs in black if they are direct child of <body> element. Other paragraphs put inside other elements like <div> or <td> would not have any effect of this rule.
The Attribute Selectors
You can also apply styles to HTML elements with particular attributes. The style rule below will match all the input elements having a type attribute with a value of text −
input[type = "text"] { color: #000000; }The advantage to this method is that the <input type = "submit" /> element is unaffected, and the color applied only to the desired text fields.
There are following rules applied to attribute selector.
- p[lang] − Selects all paragraph elements with a lang attribute.
- p[lang="fr"] − Selects all paragraph elements whose lang attribute has a value of exactly "fr".
- p[lang~="fr"] − Selects all paragraph elements whose lang attribute contains the word "fr".
- p[lang|="en"] − Selects all paragraph elements whose lang attribute contains values that are exactly "en", or begin with "en-".
Multiple Style Rules
You may need to define multiple style rules for a single element. You can define these rules to combine multiple properties and corresponding values into a single block as defined in the following example −
h1 { color: #36C; font-weight: normal; letter-spacing: .4em; margin-bottom: 1em; text-transform: lowercase;}Here all the property and value pairs are separated by a semicolon (;). You can keep them in a single line or multiple lines. For better readability, we keep them in separate lines.
For a while, don't bother about the properties mentioned in the above block. These properties will be explained in the coming chapters and you can find complete detail about properties in CSS References
Grouping Selectors
You can apply a style to many selectors if you like. Just separate the selectors with a comma, as given in the following example −
h1, h2, h3 { color: #36C; font-weight: normal; letter-spacing: .4em; margin-bottom: 1em; text-transform: lowercase;}This define style rule will be applicable to h1, h2 and h3 element as well. The order of the list is irrelevant. All the elements in the selector will have the corresponding declarations applied to them.
You can combine the various id selectors together as shown below −
#content, #footer, #supplement { position: absolute; left: 510px; width: 200px;}CSS - Inclusion
<head> <style type = "text/css" media = "all"> body { background-color: linen; } h1 { color: maroon; margin-left: 40px; } </style> </head> <body> <h1>This is a heading</h1> <p>This is a paragraph.</p> </body> </html>
It will produce the following result −
Attributes
Attributes associated with <style> elements are −
Inline CSS - The style Attribute
You can use style attribute of any HTML element to define style rules. These rules will be applied to that element only. Here is the generic syntax −
<element style = "...style rules....">
Attributes
Example
Following is the example of inline CSS based on the above syntax −
<html> <head> </head>
<body> <h1 style = "color:#36C;"> This is inline CSS </h1> </body></html>It will produce the following result −
External CSS - The <link> Element
The <link> element can be used to include an external stylesheet file in your HTML document.
An external style sheet is a separate text file with .css extension. You define all the Style rules within this text file and then you can include this file in any HTML document using <link> element.
Here is the generic syntax of including external CSS file −
<head> <link type = "text/css" href = "..." media = "..." /></head>
Attributes
Attributes associated with <style> elements are −
Example
Consider a simple style sheet file with a name mystyle.css having the following rules −
h1, h2, h3 { color: #36C; font-weight: normal; letter-spacing: .4em; margin-bottom: 1em; text-transform: lowercase;}Now you can include this file mystyle.css in any HTML document as follows −
<head> <link type = "text/css" href = "mystyle.css" media = " all" /></head>Imported CSS - @import Rule
@import is used to import an external stylesheet in a manner similar to the <link> element. Here is the generic syntax of @import rule.
<head> @import "URL";</head>Here URL is the URL of the style sheet file having style rules. You can use another syntax as well −
<head> @import url("URL");</head>Example
Following is the example showing you how to import a style sheet file into HTML document −
<head> @import "mystyle.css";</head>
CSS Rules Overriding
We have discussed four ways to include style sheet rules in a an HTML document. Here is the rule to override any Style Sheet Rule.
- Any inline style sheet takes highest priority. So, it will override any rule defined in <style>...</style> tags or rules defined in any external style sheet file.
- Any rule defined in <style>...</style> tags will override rules defined in any external style sheet file.
- Any rule defined in external style sheet file takes lowest priority, and rules defined in this file will be applied only when above two rules are not applicable.
Handling old Browsers
There are still many old browsers who do not support CSS. So, we should take care while writing our Embedded CSS in an HTML document. The following snippet shows how you can use comment tags to hide CSS from older browsers −
<style type = "text/css"> <!-- body, td { color: blue; } --></style>CSS Comments
Many times, you may need to put additional comments in your style sheet blocks. So, it is very easy to comment any part in style sheet. You can simple put your comments inside /*.....this is a comment in style sheet.....*/.
You can use /* ....*/ to comment multi-line blocks in similar way you do in C and C++ programming languages.
Example
<!DOCTYPE html><html> <head> <style> p { color: red; /* This is a single-line comment */ text-align: center; } /* This is a multi-line comment */ </style> </head>
<body> <p>Hello World!</p> </body></html>It will produce the following result −
CSS - Measurement Units
CSS - Colors
These formats are explained in more detail in the following sections −
CSS Colors - Hex Codes
A hexadecimal is a 6 digit representation of a color. The first two digits(RR) represent a red value, the next two are a green value(GG), and the last are the blue value(BB).
A hexadecimal is a 6 digit representation of a color. The first two digits(RR) represent a red value, the next two are a green value(GG), and the last are the blue value(BB).
A hexadecimal value can be taken from any graphics software like Adobe Photoshop, Jasc Paintshop Pro, or even using Advanced Paint Brush.
Each hexadecimal code will be preceded by a pound or hash sign '#'. Following are the examples to use Hexadecimal notation.
CSS Colors - Short Hex Codes
This is a shorter form of the six-digit notation. In this format, each digit is replicated to arrive at an equivalent six-digit value. For example: #6A7 becomes #66AA77.
A hexadecimal value can be taken from any graphics software like Adobe Photoshop, Jasc Paintshop Pro, or even using Advanced Paint Brush.
Each hexadecimal code will be preceded by a pound or hash sign '#'. Following are the examples to use Hexadecimal notation.
CSS Colors - RGB Values
This color value is specified using the rgb( ) property. This property takes three values, one each for red, green, and blue. The value can be an integer between 0 and 255 or a percentage.
NOTE − All the browsers does not support rgb() property of color so it is recommended not to use it.
Following is the example to show few colors using RGB values.
Building Color Codes
You can build millions of color codes using our Color Code Builder. Check our HTML Color Code Builder. To use this tool, you would need a Java Enabled Browser.
Browser Safe Colors
Here is the list of 216 colors which are supposed to be most safe and computer independent colors. These colors vary from hexa code 000000 to FFFFFF. These colors are safe to use because they ensure that all computers would display the colors correctly when running a 256 color palette −
CSS - Backgrounds
Set the Background Color
Following is the example which demonstrates how to set the background color for an element.
<html> <head> </head>
<body> <p style = "background-color:yellow;"> This text has a yellow background color. </p> </body></html> This will produce following result −
Set the Background Image
We can set the background image by calling local stored images as shown below −
<html> <head> <style> body { background-image: url("/css/images/css.jpg"); background-color: #cccccc; } </style> </head> <body> <h1>Hello World!</h1> </body><html>It will produce the following result −
Repeat the Background Image
The following example demonstrates how to repeat the background image if an image is small. You can use no-repeat value for background-repeat property if you don't want to repeat an image, in this case image will display only once.
By default background-repeat property will have repeat value.
<html> <head> <style> body { background-image: url("/css/images/css.jpg"); background-repeat: repeat; } </style> </head>
<body> <p>Tutorials point</p> </body></html>It will produce the following result −
The following example which demonstrates how to repeat the background image vertically.
<html> <head> <style> body { background-image: url("/css/images/css.jpg"); background-repeat: repeat-y; } </style> </head>
<body> <p>Tutorials point</p> </body></html>It will produce the following result −
The following example demonstrates how to repeat the background image horizontally.
<html> <head> <style> body { background-image: url("/css/images/css.jpg"); background-repeat: repeat-x; } </style> </head> <body> <p>Tutorials point</p> </body></html>It will produce the following result −

<body> <p>Tutorials point</p> </body></html>It will produce the following result −
Set the Background Attachment
Background attachment determines whether a background image is fixed or scrolls with the rest of the page.
The following example demonstrates how to set the fixed background image.
<!DOCTYPE html><html> <head> <style> body { background-image: url('/css/images/css.jpg'); background-repeat: no-repeat; background-attachment: fixed; } </style> </head>
<body> <p>The background-image is fixed. Try to scroll down the page.</p> <p>The background-image is fixed. Try to scroll down the page.</p> <p>The background-image is fixed. Try to scroll down the page.</p> <p>The background-image is fixed. Try to scroll down the page.</p> <p>The background-image is fixed. Try to scroll down the page.</p> <p>The background-image is fixed. Try to scroll down the page.</p> <p>The background-image is fixed. Try to scroll down the page.</p> <p>The background-image is fixed. Try to scroll down the page.</p> <p>The background-image is fixed. Try to scroll down the page.</p> </body></html>It will produce the following result −
The following example demonstrates how to set the scrolling background image.
<!DOCTYPE html><html> <head> <style> body { background-image: url('/css/images/css.jpg'); background-repeat: no-repeat; background-attachment: fixed; background-attachment:scroll; } </style> </head>
<body> <p>The background-image is fixed. Try to scroll down the page.</p> <p>The background-image is fixed. Try to scroll down the page.</p> <p>The background-image is fixed. Try to scroll down the page.</p> <p>The background-image is fixed. Try to scroll down the page.</p> <p>The background-image is fixed. Try to scroll down the page.</p> <p>The background-image is fixed. Try to scroll down the page.</p> <p>The background-image is fixed. Try to scroll down the page.</p> <p>The background-image is fixed. Try to scroll down the page.</p> <p>The background-image is fixed. Try to scroll down the page.</p> </body></html>It will produce the following result −
Shorthand Property
You can use the background property to set all the background properties at once. For example −
<p style = "background:url(/images/pattern1.gif) repeat fixed;"> This parapgraph has fixed repeated background image.</p>
CSS - Fonts

CSS - Using Images
The Image Border Property
The border property of an image is used to set the width of an image border. This property can have a value in length or in %.
A width of zero pixels means no border.
Here is the example −
<html> <head> </head>
<body> <img style = "border:0px;" src = "/css/images/logo.png" /> <br /> <img style = "border:3px dashed red;" src = "/css/images/logo.png" /> </body></html> It will produce the following result −
The Image Height Property
The height property of an image is used to set the height of an image. This property can have a value in length or in %. While giving value in %, it applies it in respect of the box in which an image is available.
Here is an example −
<html> <head> </head>
<body> <img style = "border:1px solid red; height:100px;" src = "/css/images/logo.png" /> <br /> <img style = "border:1px solid red; height:50%;" src = "/css/images/logo.png" /> </body></html> It will produce the following result −
The Image Width Property
The width property of an image is used to set the width of an image. This property can have a value in length or in %. While giving value in %, it applies it in respect of the box in which an image is available.
Here is an example −
<html> <head> </head>
<body> <img style = "border:1px solid red; width:150px;" src = "/css/images/logo.png" /> <br /> <img style = "border:1px solid red; width:100%;" src = "/css/images/logo.png" /> </body></html> It will produce the following result −
The -moz-opacity Property
The -moz-opacity property of an image is used to set the opacity of an image. This property is used to create a transparent image in Mozilla. IE uses filter:alpha(opacity=x) to create transparent images.
In Mozilla (-moz-opacity:x) x can be a value from 0.0 - 1.0. A lower value makes the element more transparent (The same things goes for the CSS3-valid syntax opacity:x).
In IE (filter:alpha(opacity=x)) x can be a value from 0 - 100. A lower value makes the element more transparent.
Here is an example −
<html> <head> </head>
<body> <img style = "border:1px solid red; -moz-opacity:0.4; filter:alpha(opacity=40);" src = "/css/images/logo.png" /> </body></html> It will produce the following result −
CSS - Links
Usually, all these properties are kept in the header part of the HTML document.
Remember a:hover MUST come after a:link and a:visited in the CSS definition in order to be effective. Also, a:active MUST come after a:hover in the CSS definition as follows −
<style type = "text/css"> a:link {color: #000000} a:visited {color: #006600} a:hover {color: #FFCC00} a:active {color: #FF00CC}</style>
Now, we will see how to use these properties to give different effects to hyperlinks.
Set the Color of Links
The following example demonstrates how to set the link color. Possible values could be any color name in any valid format.
<html> <head> <style type = "text/css"> a:link {color:#000000} </style> </head>
<body> <a href = "">Link</a> </body></html> It will produce the following black link −
Set the Color of Visited Links
The following example demonstrates how to set the color of visited links. Possible values could be any color name in any valid format.
<html> <head> <style type = "text/css"> a:visited {color: #006600} </style> </head>
<body> <a href = ""> link</a> </body></html> It will produce the following link. Once you will click this link, it will change its color to green.
Change the Color of Links when Mouse is Over
The following example demonstrates how to change the color of links when we bring a mouse pointer over that link. Possible values could be any color name in any valid format.
<html> <head> <style type = "text/css"> a:hover {color: #FFCC00} </style> </head>
<body> <a href = "">Link</a> </body></html> It will produce the following link. Now, you bring your mouse over this link and you will see that it changes its color to yellow.
Change the Color of Active Links
The following example demonstrates how to change the color of active links. Possible values could be any color name in any valid format.
<html> <head> <style type = "text/css"> a:active {color: #FF00CC} </style> </head>
<body> <a href = "">Link</a> </body></html> It will produce the following link. It will change its color to pink when the user clicks it.
CSS - Tables
Now, we will see how to use these properties with examples.
The border-collapse Property
This property can have two values collapse and separate. The following example uses both the values −
<html> <head> <style type = "text/css"> table.one {border-collapse:collapse;} table.two {border-collapse:separate;} td.a { border-style:dotted; border-width:3px; border-color:#000000; padding: 10px; } td.b { border-style:solid; border-width:3px; border-color:#333333; padding:10px; } </style> </head>
<body> <table class = "one"> <caption>Collapse Border Example</caption> <tr><td class = "a"> Cell A Collapse Example</td></tr> <tr><td class = "b"> Cell B Collapse Example</td></tr> </table> <br /> <table class = "two"> <caption>Separate Border Example</caption> <tr><td class = "a"> Cell A Separate Example</td></tr> <tr><td class = "b"> Cell B Separate Example</td></tr> </table> </body></html>It will produce the following result −
The border-spacing Property
The border-spacing property specifies the distance that separates adjacent cells'. borders. It can take either one or two values; these should be units of length.
If you provide one value, it will applies to both vertical and horizontal borders. Or you can specify two values, in which case, the first refers to the horizontal spacing and the second to the vertical spacing −
NOTE − Unfortunately, this property does not work in Netscape 7 or IE 6.
<style type="text/css"> /* If you provide one value */ table.example {border-spacing:10px;} /* This is how you can provide two values */ table.example {border-spacing:10px; 15px;}</style>
Now let's modify the previous example and see the effect −
<html> <head> <style type = "text/css"> table.one { border-collapse:separate; width:400px; border-spacing:10px; } table.two { border-collapse:separate; width:400px; border-spacing:10px 50px; } </style> </head>

<html> <head> <style type = "text/css"> .scroll { display:block; border: 1px solid red; padding:5px; margin-top:5px; width:300px; height:50px; overflow:scroll; } .auto { display:block; border: 1px solid red; padding:5px; margin-top:5px; width:300px; height:50px; overflow:auto; } </style> </head>
<body> <p>Example of scroll value:</p> <div class = "scroll"> I am going to keep lot of content here just to show you how scrollbars works if there is an overflow in an element box. This provides your horizontal as well as vertical scrollbars. </div> <br /> <p>Example of auto value:</p> <div class = "auto"> I am going to keep lot of content here just to show you how scrollbars works if there is an overflow in an element box. This provides your horizontal as well as vertical scrollbars. </div> </body></html> It will produce the following result −
CSS - Visibility
Here is an example −
<html> <head> </head>
<body> <p> This paragraph should be visible in normal way. </p> <p style = "visibility:hidden;"> This paragraph should not be visible. </p> </body></html> It will produce the following result −
CSS - Positioning
- Move Up - Use a negative value for top.
- Move Down - Use a positive value for top.
NOTE − You can use bottom or right values as well in the same way as top and left.
Here is the example −
<html> <head> </head>
<body> <div style = "position:relative; left:80px; top:2px; background-color:yellow;"> This div has relative positioning. </div> </body></html>It will produce the following result −
Absolute Positioning
An element with position: absolute is positioned at the specified coordinates relative to your screen top-left corner.
You can use two values top and left along with the position property to move an HTML element anywhere in the HTML document.
- Move Left - Use a negative value for left.
- Move Right - Use a positive value for left.
- Move Up - Use a negative value for top.
- Move Down - Use a positive value for top.
NOTE − You can use bottom or right values as well in the same way as top and left.
Here is an example −
<html> <head> </head>
<body> <div style = "position:absolute; left:80px; top:20px; background-color:yellow;"> This div has absolute positioning. </div> </body></html> Fixed Positioning
Fixed positioning allows you to fix the position of an element to a particular spot on the page, regardless of scrolling. Specified coordinates will be relative to the browser window.
You can use two values top and left along with the position property to move an HTML element anywhere in the HTML document.
- Move Left - Use a negative value for left.
- Move Right - Use a positive value for left.
- Move Up - Use a negative value for top.
- Move Down - Use a positive value for top.
NOTE − You can use bottom or right values as well in the same way as top and left.
Here is an example −
<html> <head> </head>
<body> <div style = "position:fixed; left:80px; top:20px; background-color:yellow;"> This div has fixed positioning. </div> </body></html>CSS - Layers
<body> <div style = "background-color:red; width:300px; height:100px; position:relative; top:10px; left:80px; z-index:2"> </div> <div style = "background-color:yellow; width:300px; height:100px; position:relative; top:-60px; left:35px; z-index:1;"> </div> <div style = "background-color:green; width:300px; height:100px; position:relative; top:-220px; left:120px; z-index:3;"> </div></body>It will produce the following result −
CSS - Pseudo Classes
The most commonly used pseudo-classes are as follows −
While defining pseudo-classes in a <style>...</style> block, following points should be noted −
- a:hover MUST come after a:link and a:visited in the CSS definition in order to be effective.
- a:active MUST come after a:hover in the CSS definition in order to be effective.
- Pseudo-class names are not case-sensitive.
- Pseudo-class are different from CSS classes but they can be combined.
The :link pseudo-class
The following example demonstrates how to use the :link class to set the link color. Possible values could be any color name in any valid format.
<html> <head> <style type = "text/css"> a:link {color:#000000} </style> </head>
<body> <a href = "">Black Link</a> </body></html>It will produce the following black link −
The :visited pseudo-class
The following is the example which demonstrates how to use the :visited class to set the color of visited links. Possible values could be any color name in any valid format.
<html> <head> <style type = "text/css"> a:visited {color: #006600} </style> </head>
<body> <a href = "">Click this link</a> </body></html> This will produce following link. Once you will click this link, it will change its color to green.
The :hover pseudo-class
The following example demonstrates how to use the :hover class to change the color of links when we bring a mouse pointer over that link. Possible values could be any color name in any valid format.
<html> <head> <style type = "text/css"> a:hover {color: #FFCC00} </style> </head>
<body> <a href = "">Bring Mouse Here</a> </body></html> It will produce the following link. Now you bring your mouse over this link and you will see that it changes its color to yellow.
The :active pseudo-class
The following example demonstrates how to use the :active class to change the color of active links. Possible values could be any color name in any valid format.
<html> <head> <style type = "text/css"> a:active {color: #FF00CC} </style> </head>
<body> <a href = "">Click This Link</a> </body></html> It will produce the following link. When a user clicks it, the color changes to pink.
The :focus pseudo-class
The following example demonstrates how to use the :focus class to change the color of focused links. Possible values could be any color name in any valid format.
<html> <head> <style type = "text/css"> a:focus {color: #0000FF} </style> </head>
<body> <a href = "">Click this Link</a> </body></html> It will produce the following link. When this link gets focused, its color changes to orange. The color changes back when it loses focus.
The :first-child pseudo-class
The :first-child pseudo-class matches a specified element that is the first child of another element and adds special style to that element that is the first child of some other element.
To make :first-child work in IE <!DOCTYPE> must be declared at the top of document.
For example, to indent the first paragraph of all <div> elements, you could use this definition −
<html> <head> <style type = "text/css"> div > p:first-child { text-indent: 25px; } </style> </head>
<body> <div> <p>First paragraph in div. This paragraph will be indented</p> <p>Second paragraph in div. This paragraph will not be indented</p> </div> <p>But it will not match the paragraph in this HTML:</p> <div> <h3>Heading</h3> <p>The first paragraph inside the div. This paragraph will not be effected.</p> </div> </body></html>It will produce the following result −
The :lang pseudo-class
The language pseudo-class :lang, allows constructing selectors based on the language setting for specific tags.
This class is useful in documents that must appeal to multiple languages that have different conventions for certain language constructs. For example, the French language typically uses angle brackets (< and >) for quoting purposes, while the English language uses quote marks (' and ').
In a document that needs to address this difference, you can use the :lang pseudo-class to change the quote marks appropriately. The following code changes the <blockquote> tag appropriately for the language being used −
<html> <head> <style type = "text/css"> /* Two levels of quotes for two languages*/ :lang(en) { quotes: '"' '"' "'" "'"; } :lang(fr) { quotes: "<<" ">>" "<" ">"; } </style> </head> <body> <p>...<q lang = "fr">A quote in a paragraph</q>...</p> </body></html>The :lang selectors will apply to all the elements in the document. However, not all elements make use of the quotes property, so the effect will be transparent for most elements.
It will produce the following result −
CSS - Pseudo Elements
The most commonly used pseudo-elements are as follows −
The :first-line pseudo-element
The following example demonstrates how to use the :first-line element to add special effects to the first line of elements in the document.
<html> <head> <style type = "text/css"> p:first-line { text-decoration: underline; } p.noline:first-line { text-decoration: none; } </style> </head>
<body> <p class = "noline"> This line would not have any underline because this belongs to nline class. </p> <p> The first line of this paragraph will be underlined as defined in the CSS rule above. Rest of the lines in this paragraph will remain normal. This example shows how to use :first-line pseduo element to give effect to the first line of any HTML element. </p> </body></html>It will produce the following link −
The :first-letter pseudo-element
The following example demonstrates how to use the :first-letter element to add special effects to the first letter of elements in the document.
<html> <head> <style type = "text/css"> p:first-letter { font-size: 5em; } p.normal:first-letter { font-size: 10px; } </style> </head>
<body> <p class = "normal"> First character of this paragraph will be normal and will have font size 10 px; </p> <p> The first character of this paragraph will be 5em big as defined in the CSS rule above. Rest of the characters in this paragraph will remain normal. This example shows how to use :first-letter pseduo element to give effect to the first characters of any HTML element. </p> </body></html>It will produce the following black link −
The :before pseudo-element
The following example demonstrates how to use the :before element to add some content before any element.
<html> <head> <style type = "text/css"> p:before { content: url(/images/bullet.gif) } </style> </head>
<body> <p> This line will be preceded by a bullet.</p> <p> This line will be preceded by a bullet.</p> <p> This line will be preceded by a bullet.</p> </body></html>It will produce the following black link −
The :after pseudo-element
The following example demonstrates how to use the :after element to add some content after any element.
<html> <head> <style type = "text/css"> p:after { content: url(/images/bullet.gif) } </style> </head>
<body> <p> This line will be succeeded by a bullet.</p> <p> This line will be succeeded by a bullet.</p> <p> This line will be succeeded by a bullet.</p> </body></html>It will produce the following black link −
CSS - @ Rules
The @import rule
The @import rule allows you to import styles from another style sheet. It should appear right at the start of the style sheet before any of the rules, and its value is a URL.
It can be written in one of the two following ways −
<style type = "text/css"> <!-- @import "mystyle.css"; or @import url("mystyle.css"); .......other CSS rules ..... --></style>The significance of the @import rule is that it allows you to develop your style sheets with a modular approach. You can create various style sheets and then include them wherever you need them.
The @charset Rule
If you are writing your document using a character set other than ASCII or ISO-8859-1 you might want to set the @charset rule at the top of your style sheet to indicate what character set the style sheet is written in.
The @charset rule must be written right at the beginning of the style sheet without even a space before it. The value is held in quotes and should be one of the standard character-sets. For example −
<style type = "text/css"> <!-- @charset "iso-8859-1" .......other CSS rules ..... --></style>The @font-face Rule
The @font-face rule is used to exhaustively describe a font face for use in a document. @font-face may also be used to define the location of a font for download, although this may run into implementation-specific limits.
In general, @font-face is extremely complicated, and its use is not recommended for any except those who are expert in font metrics.
Here is an example −
<style type = "text/css"> <!-- @font-face { font-family: "Scarborough Light"; src: url("http://www.font.site/s/scarbo-lt"); } @font-face { font-family: Santiago; src: local ("Santiago"), url("http://www.font.site/s/santiago.tt") format("truetype"); unicode-range: U+??,U+100-220; font-size: all; font-family: sans-serif; } --></style>The !important Rule
Cascading Style Sheets cascade. It means that the styles are applied in the same order as they are read by the browser. The first style is applied and then the second and so on.
The !important rule provides a way to make your CSS cascade. It also includes the rules that are to be applied always. A rule having a !important property will always be applied, no matter where that rule appears in the CSS document.
For example, in the following style sheet, the paragraph text will be black, even though the first style property applied is red:
<style type = "text/css"> <!-- p { color: #ff0000; } p { color: #000000; } --></style>So, if you wanted to make sure that a property always applied, you would add the !important property to the tag. So, to make the paragraph text always red, you should write it as follows −
<html> <head> <style type = "text/css"> p { color: #ff0000 !important; } p { color: #000000; } </style> </head>
<body> <p>Tutorialspoint.com</p> </body></html> Here you have made p { color: #ff0000 !important; } mandatory, now this rule will always apply even you have defined another rule p { color: #000000; }
It will produce the following result −

In HTML 4.0, the media attribute on the LINK element specifies the target media of an external style sheet −
Following is an example −
<style tyle = "text/css"> <!-- <!doctype html public "-//w3c//dtd html 4.0//en"> <html> <head> <title>link to a target medium</title> <link rel = "stylesheet" type = "text/css" media = "print, handheld" href = "foo.css"> </head>
<body> <p>the body... </body> </html> --></style>Recognized Media Types
The names chosen for CSS media types reflect target devices for which the relevant properties make sense. They give a sense of what device the media type is meant to refer to. Given below is a list of various media types −
NOTE − Media type names are case-insensitive.
CSS Paged Media - @page Rule
The CSS2 defines a "page box", a box of finite dimensions in which content is rendered. The page box is a rectangular region that contains two areas −
- The page area − The page area includes the boxes laid out on that page. The edges of the page area act as the initial containing block for layout that occurs between page breaks.
- The margin area − It surrounds the page area.
You can specify the dimensions, orientation, margins, etc., of a page box within an @page rule. The dimensions of the page box are set with the 'size' property. The dimensions of the page area are the dimensions of the page box minus the margin area.
For example, the following @page rule sets the page box size to 8.5 × 11 inches and creates '2cm' margin on all sides between the page box edge and the page area −
<style type = "text/css"> <!-- @page { size:8.5in 11in; margin: 2cm } --></style>You can use the margin, margin-top, margin-bottom, margin-left, and margin-right properties within the @page rule to set margins for your page.
Finally, the marks property is used within the @page rule to create crop and registration marks outside the page box on the target sheet. By default, no marks are printed. You may use one or both of the crop and cross keywords to create crop marks and registration marks, respectively, on the target print page.
Setting Page Size
The size property specifies the size and orientation of a page box. There are four values which can be used for page size −
- auto − The page box will be set to the size and orientation of the target sheet.
- landscape − Overrides the target's orientation. The page box is the same size as the target, and the longer sides are horizontal.
- portrait − Overrides the target's orientation. The page box is the same size as the target, and the shorter sides are horizontal.
- length − Length values for the 'size' property create an absolute page box. If only one length value is specified, it sets both the width and height of the page box. Percentage values are not allowed for the 'size' property.
In the following example, the outer edges of the page box will align with the target. The percentage value on the 'margin' property is relative to the target size so if the target sheet dimensions are 21.0cm × 29.7cm (i.e., A4), the margins are 2.10cm and 2.97cm.
<style type = "text/css"> <!-- @page { size: auto; /* auto is the initial value */ margin: 10%; } --></style>The following example sets the width of the page box to be 8.5 inches and the height to be 11 inches. The page box in this example requires a target sheet size of 8.5" × 11" or larger.
<style type = "text/css"> <!-- @page { size: 8.5in 11in; /* width height */ } --></style>Once you create a named page layout, you can use it in your document by adding the page property to a style that is later applied to an element in your document. For example, this style renders all the tables in your document on landscape pages −
<style type = "text/css"> <!-- @page { size : portrait } @page rotated { size : landscape } table { page : rotated } --></style>
Due to the above rule, while printing, if the browser encounters a <table> element in your document and the current page layout is the default portrait layout, it starts a new page and prints the table on a landscape page.
Left, Right, and First pages
When printing double-sided documents, the page boxes on left and right pages should be different. It can be expressed through two CSS pseudo-classes as follows −
<style type = "text/css"> <!-- @page :left { margin-left: 4cm; margin-right: 3cm; }
@page :right { margin-left: 3cm; margin-right: 4cm; } --></style>You can specify the style for the first page of a document with the :first pseudo-class −
<style type = "text/css"> <!-- @page { margin: 2cm } /* All margins set to 2cm */
@page :first { margin-top: 10cm /* Top margin on first page 10cm */ } --></style>Controlling Pagination
Unless you specify otherwise, page breaks occur only when the page format changes or when the content overflows the current page box. To otherwise force or suppress page breaks, use the page-break-before, page-break-after, and page-break-inside properties.
Both the page-break-before and page-break-after accept the auto, always, avoid, left, and right keywords.
The keyword auto is the default, it lets the browser generate page breaks as needed. The keyword always forces a page break before or after the element, while avoid suppresses a page break immediately before or after the element. The left and right keywords force one or two page breaks, so that the element is rendered on a left-hand or right-hand page.
Using pagination properties is quite straightforward. Suppose your document has level-1 headers start new chapters with level-2 headers to denote sections. You'd like each chapter to start on a new, right-hand page, but you don't want section headers to be split across a page break from the subsequent content. You can achieve this using following rule −
<style type = "text/css"> <!-- h1 { page-break-before : right } h2 { page-break-after : avoid } --></style>Use only the auto and avoid values with the page-break-inside property. If you prefer that your tables not be broken across pages if possible, you would write the rule −
<style type = "text/css"> <!-- table { page-break-inside : avoid } --></style>Controlling Widows and Orphans
In typographic lingo, orphans are those lines of a paragraph stranded at the bottom of a page due to a page break, while widows are those lines remaining at the top of a page following a page break. Generally, printed pages do not look attractive with single lines of text stranded at the top or bottom. Most printers try to leave at least two or more lines of text at the top or bottom of each page.
- The orphans property specifies the minimum number of lines of a paragraph that must be left at the bottom of a page.
- The widows property specifies the minimum number of lines of a paragraph that must be left at the top of a page.
Here is the example to create 4 lines at the bottom and 3 lines at the top of each page −
<style type = "text/css"> <!-- @page{orphans:4; widows:2;} --></style>CSS - Aural Media
- Medical documentation
When using aural properties, the canvas consists of a three-dimensional physical space (sound surrounds) and a temporal space (one may specify sounds before, during, and after other sounds).
The CSS properties also allow you to vary the quality of synthesized speech (voice type, frequency, inflection, etc.).
Here is an example −
<html> <head> <style type = "text/css"> h1, h2, h3, h4, h5, h6 { voice-family: paul; stress: 20; richness: 90; cue-before: url("../audio/pop.au"); } p { azimuth:center-right; } </style> </head>
<body> <h1>Tutorialspoint.com</h1> <h2>Tutorialspoint.com</h2> <h3>Tutorialspoint.com</h3> <h4>Tutorialspoint.com</h4> <h5>Tutorialspoint.com</h5> <h6>Tutorialspoint.com</h6> <p>Tutorialspoint.com</p> </body></html> It will produce the following result −
It will direct the speech synthesizer to speak headers in a voice (a kind of audio font) called "paul", on a flat tone, but in a very rich voice. Before speaking the headers, a sound sample will be played from the given URL.
Paragraphs with class ‘heidi’ will appear to come from front left (if the sound system is capable of spatial audio), and paragraphs of class ‘peter’ from the right.
Now we will see the various properties related to aural media.

The azimuth Property
The azimuth property sets where the sound should come from horizontally. The possible values are listed below −
- angle − Position is described in terms of an angle within the range -360deg to 360deg. The value 0deg means directly ahead in the center of the sound stage. 90deg is to the right, 180deg behind, and 270deg (or, equivalently and more conveniently, -90deg) to the left.
- left-side − Same as '270deg'. With 'behind', '270deg'.
- far-left − Same as '300deg'. With 'behind', '240deg'.
- left − Same as '320deg'. With 'behind', '220deg'.
- center-left − Same as '340deg'. With 'behind', '200deg'.
- center − Same as '0deg'. With 'behind', '180deg'.
- center-right − Same as '20deg'. With 'behind', '160deg'.
- right − Same as '40deg'. With 'behind', '140deg'.
- far-right − Same as '60deg'. With 'behind', '120deg'.
- right-side − Same as '90deg'. With 'behind', '90deg'.
- leftwards − Moves the sound to the left and relative to the current angle. More precisely, subtracts 20 degrees.
- rightwards − Moves the sound to the right, relative to the current angle. More precisely, adds 20 degrees.
Here is an example −
<style type = "text/css"> <!-- h1 { azimuth: 30deg } td.a { azimuth: far-right } /* 60deg */ #12 { azimuth: behind far-right } /* 120deg */ p.comment { azimuth: behind } /* 180deg */ --></style>The elevation Property
The elevation property sets where the sound should come from vertically. The possible values are as follows −
- angle − Specifies the elevation as an angle, between -90deg and 90deg. 0deg means on the forward horizon, which loosely means level with the listener. 90deg means directly overhead and -90deg means directly below.
- below − Same as '-90deg'.
- level − Same as '0deg'.
- above − Same as '90deg'.
- higher − Adds 10 degrees to the current elevation.
- lower − Subtracts 10 degrees from the current elevation.
Here is an example −
<style type = "text/css"> <!-- h1 { elevation: above } tr.a { elevation: 60deg } tr.b { elevation: 30deg } tr.c { elevation: level } --></style>The cue-after Property
The cue-after property specifies a sound to be played after speaking an element's content to delimit it from other. The possible values include −
- url − The URL of a sound file to be played.
- none − Nothing has to be played.
Here is an example −
<style type = "text/css"> <!-- a {cue-after: url("dong.wav");} h1 {cue-after: url("pop.au"); } --></style>The cue-before Property
This property specifies a sound to be played before speaking an element's content to delimit it from other. The possible values are −
- url − The URL of a sound file to be played.
- none − Nothing has to be played.
Here is an example −
<style type = "text/css"> <!-- a {cue-before: url("bell.aiff");} h1 {cue-before: url("pop.au"); } --></style>The cue Property
The cue property is a shorthand for setting cue-before and cue-after. If two values are given, the first value is cue-before and the second is cue-after. If only one value is given, it applies to both properties.
For example, the following two rules are equivalent −
<style type = "text/css"> <!-- h1 {cue-before: url("pop.au"); cue-after: url("pop.au") } h1 {cue: url("pop.au") } --></style>The pause-after Property
This property specifies a pause to be observed after speaking an element's content. The possible values are −
- time − Expresses the pause in absolute time units (seconds and milliseconds).
- percentage − Refers to the inverse of the value of the speech-rate property. For example, if the speech-rate is 120 words per minute (i.e. a word takes half a second, or 500ms), then a pause-after of 100% means a pause of 500 ms and a pause-after of 20% means 100ms.
The pause-before Property
This property specifies a pause to be observed before speaking an element's content. The possible values are −
- time − Expresses the pause in absolute time units (seconds and milliseconds).
- percentage − Refers to the inverse of the value of the speech-rate property. For example, if the speech-rate is 120 words per minute (i.e. a word takes half a second, or 500ms), then a pause-before of 100% means a pause of 500 ms and a pause-before of 20% means 100ms.
The pause Property
This property is a shorthand for setting pause-before and pause-after. If two values are given, the first value is pause-before and the second is pause-after.
Here is an example −
<style type = "text/css"> <!-- /* pause-before: 20ms; pause-after: 20ms */ h1 { pause : 20ms } /* pause-before: 30ms; pause-after: 40ms */ h2{ pause : 30ms 40ms } /* pause-before: ?; pause-after: 10ms */ h3 { pause-after : 10ms } --></style>The pitch Property
This property specifies the average pitch (a frequency) of the speaking voice. The average pitch of a voice depends on the voice family. For example, the average pitch for a standard male voice is around 120Hz, but for a female voice, it's around 210Hz. The possible values are −
- frequency − Specifies the average pitch of the speaking voice in hertz (Hz).
- x-low, low, medium, high, x-high − These values do not map to absolute frequencies since these values depend on the voice family.
The pitch-range Property
This property specifies variation in average pitch. The possible values are −
- number − A value between '0' and '100'. A pitch range of '0' produces a flat, monotonic voice. A pitch range of 50 produces normal inflection. Pitch ranges greater than 50 produce animated voices.
The play-during Property
This property specifies a sound to be played as a background while an element's content is spoken. Possible values could be any of the followings −
- URI − The sound designated by this <uri> is played as a background while the element's content is spoken.
- mix − When present, this keyword means that the sound inherited from the parent element's play-during property continues to play and the sound designated by the uri is mixed with it. If mix is not specified, the element's background sound replaces the parent's.
- repeat − When present, this keyword means that the sound will repeat if it is too short to fill the entire duration of the element. Otherwise, the sound plays once and then stops.
- auto − The sound of the parent element continues to play.
- none − This keyword means that there is silence.
Here is an example −
<style type = "text/css"> <!-- blockquote.sad { play-during: url("violins.aiff") } blockquote q { play-during: url("harp.wav") mix } span.quiet { play-during: none } --></style>The richness Property
This property specifies the richness or brightness of the speaking voice. The possible values are −
- number − A value between '0' and '100'. The higher the value, the more the voice will carry. A lower value will produce a soft, mellifluous voice.
The speak Property
This property specifies whether text will be rendered aurally and if so, in what manner. The possible values are −
- none − Suppresses aural rendering so that the element requires no time to render.
- normal − Uses language-dependent pronunciation rules for rendering an element and its children.
- spell-out − Spells the text one letter at a time.
Note the difference between an element whose 'volume' property has a value of 'silent' and an element whose 'speak' property has the value 'none'. The former takes up the same time as if it had been spoken, including any pause before and after the element, but no sound is generated. The latter requires no time and is not rendered.
The speak-numeral Property
This property controls how numerals are spoken. The possible values are −
- digits − Speak the numeral as individual digits. Thus, "237" is spoken "Two Three Seven".
- continuous − Speak the numeral as a full number. Thus, "237" is spoken "Two hundred thirty seven". Word representations are language-dependent.
The speak-punctuation Property
This property specifies how punctuation is spoken. The possible values are −
- code − Punctuation such as semicolons, braces, and so on are to be spoken literally.
- none − Punctuation is not to be spoken, but instead rendered naturally as various pauses.
The speech-rate property
This property specifies the speaking rate. Note that both absolute and relative keyword values are allowed. The possible values are −
- number − Specifies the speaking rate in words per minute.
- x-slow − Same as 80 words per minute.
- slow − Same as 120 words per minute.
- medium − Same as 180 - 200 words per minute.
- fast − Same as 300 words per minute.
- x-fast − Same as 500 words per minute.
- faster − Adds 40 words per minute to the current speech rate.
- slower − Subtracts 40 words per minutes from the current speech rate.
The stress Property
This property specifies the height of "local peaks" in the intonation contour of a voice. English is a stressed language, and different parts of a sentence are assigned primary, secondary, or tertiary stress. The possible values are −
- number − A value between '0' and '100'. The meaning of values depends on the language being spoken. For example, a level of '50' for a standard, English-speaking male voice (average pitch = 122Hz), speaking with normal intonation and emphasis would have a different meaning than '50' for an Italian voice.
The voice-family Property
The value is a comma-separated, prioritized list of voice family names. It can have following values −
- generic-voice − Values are voice families. Possible values are 'male', 'female', and 'child'.
- specific-voice − Values are specific instances (e.g., comedian, trinoids, carlos, lani).
Here is an example −
<style type = "text/css"> <!-- h1 { voice-family: announcer, male } p.part.romeo { voice-family: romeo, male } p.part.juliet { voice-family: juliet, female } --></style>The volume Property
Volume refers to the median volume of the voice. It can have following values −
- numbers − Any number between '0' and '100'. '0' represents the minimum audible volume level and 100 corresponds to the maximum comfortable level.
- percentage − These values are calculated relative to the inherited value, and are then clipped to the range '0' to '100'.
- silent − No sound at all. The value '0' does not mean the same as 'silent'.
- x-soft − Same as '0'.
- soft − Same as '25'.
- medium − Same as '50'.
- loud − Same as '75'.
- x-loud − Same as '100'.
Here is an example −
<style type = "text/css"> <!-- P.goat { volume: x-soft } --></style>Paragraphs with class goat will be very soft.
CSS Printing - @media Rule
@media print { p.bodyText {font-family:georgia, times, serif;}}@media screen, print { p.bodyText {font-size:10pt}}If you are defining your style sheet in a separate file, then you can also use the media attribute when linking to an external style sheet −
<link rel = "stylesheet" type = "text/css" media = "print" href = "mystyle.css">
CSS - Layouts
- CSS is pivotal to the future of Web documents and will be supported by most browsers.
- CSS is more exact than tables, allowing your document to be viewed as you intended, regardless of the browser window.
- Keeping track of nested tables can be a real pain. CSS rules tend to be well organized, easily read, and easily changed.
Finally, we would suggest you to use whichever technology makes sense to you and use what you know or what presents your documents in the best way.
CSS also provides table-layout property to make your tables load much faster. Following is an example −
<table style = "table-layout:fixed;width:600px;"> <tr height = "30"> <td width = "150">CSS table layout cell 1</td> <td width = "200">CSS table layout cell 2</td> <td width = "250">CSS table layout cell 3</td> </tr></table>You will notice the benefits more on large tables. With traditional HTML, the browser had to calculate every cell before finally rendering the table. When you set the table-layout algorithm to fixed, however, it only needs to look at the first row before rendering the whole table. It means your table will need to have fixed column widths and row heights.
Sample Column Layout
Here are the steps to create a simple Column Layout using CSS −
Set the margin and padding of the complete document as follows −
<style style = "text/css"> <!-- body { margin:9px 9px 0 9px; padding:0; background:#FFF; } --></style>Now, we will define a column with yellow color and later, we will attach this rule to a <div> −
<style style = "text/css"> <!-- #level0 { background:#FC0; } --></style>Upto this point, we will have a document with yellow body, so let us now define another division inside level0 −
<style style = "text/css"> <!-- #level1 { margin-left:143px; padding-left:9px; background:#FFF; } --></style>
Now, we will nest one more division inside level1, and we will change just background color −
<style style = "text/css"> <!-- #level2 { background:#FFF3AC; } --></style>Finally, we will use the same technique, nest a level3 division inside level2 to get the visual layout for the right column −
<style style = "text/css"> <!-- #level3 { margin-right:143px; padding-right:9px; background:#FFF; } #main { background:#CCC; } --></style>Complete the source code as follows −
<style style = "text/css"> body { margin:9px 9px 0 9px; padding:0; background:#FFF; } #level0 {background:#FC0;} #level1 { margin-left:143px; padding-left:9px; background:#FFF; } #level2 {background:#FFF3AC;} #level3 { margin-right:143px; padding-right:9px; background:#FFF; } #main {background:#CCC;}</style><body> <div id = "level0"> <div id = "level1"> <div id = "level2"> <div id = "level3"> <div id = "main"> Final Content goes here... </div> </div> </div> </div> </div></body>Similarly, you can add a top navigation bar or an ad bar at the top of the page.
It will produce the following result −
CSS - Validations
W3C CSS Validator (World Wide Web Consortium), This validator checks your css by either file upload, direct input, or using URI - one page at a time. This validator helps you to locate all the errors in your CSS.The WDG CSS check validator, lets you validate your css by direct input, file upload, and using URI. Errors will be listed by line and column numbers if you have any. Errors usually come with links to explain the reason of error.
A CSS validator checks your Cascading Style Sheets to make sure that they comply with the CSS standards set by the W3 Consortium. There are a few validators which will also tell you which CSS features are supported by which browsers (since not all browsers are equal in their CSS implementation).
Why Validate Your HTML Code?
There are a number of reasons why you should validate your code. But major ones are −
- It Helps Cross-Browser, Cross-Platform, and Future Compatibility.
- A good quality website increases search engine visibility.
- Professionalism: As a web developer, your code should not raise errors while seen by the visitors.
